Advanced Technology Hot Melt Hoses
Description
Nordson advanced-technology hot melt hoses are the
industry standard for consistent temperature control
and safe operation. Advanced-technology hoses extend
performance and durability using (Nomex®) aramid
insulation. This feature, along with thermal-sensing
accuracy, automated manufacturing and parallel
ground paths, provides unmatched performance,
durability and safety.
• Aramid insulation significantly improves chemical resistance
and moisture sensitivity.
• Chlorine-free materials eliminate hardware corrosion caused
by emissions at elevated temperatures.
• Insulation retains hose flexibility, and electrical and
mechanical properties well beyond system operating
temperatures. Insulation will not melt or support combustion
in the air.
• Four layers of overlapped aramid-felt insulation increase
thermal efficiency, control heat loss, improve durability and
reduce external temperature.
• Nordson RTD-style and TC Series Pt100 (RTD) hoses
feature area sensors that use temperature averaging over a
set hose length to generate a reliable reading of hot melt
temperature.
NOTE: Refer to information shipped with the hose for electrical
connector data.

• TC Series thermocouple (TC) hoses use point sensors at
a discrete point. Automated manufacturing maintains
consistent thermocouple positioning for accurate and
consistent temperature readings.
• Precision fabrication and calibration prior to assembly ensure
that resistance and control values match, eliminating the need
for temperature control calibration at installation.
• Low watt-density heating elements reduce hot spot potential
that can cause char.
• Closely spaced wraps deliver efficient and uniform heat
transfer for controlled startup and consistent flow rates.
• Two separate ground paths protect personnel from injury and
equipment from damage.
• Dedicated low-resistance ground reduces the possibility of
high-impedance faults.
• Electrical connections use make-first, break-last pins at the
applicator and unit ends to prevent powering the hose or
applicator without ground connection.
• Nordson RTD-style water-wash hoses have improved water
resistance and greater flexibility for tight installation. Plugs
are rated to IP67 with the Nordson hose/applicator rated
IPX6.
• Accessories include brackets, inline filters, fittings, hose
protector, and suspension support.
